IPC: H02J9/00
Filed: 1977-10-15
Abstract: PURPOSE:To provide an emergency lamp system, which includes a timer that is reset at the instance when current supply from commercial power source is started, produces a signal after passing of a time period required for charging a battery to its full capacity, and produces a lamp inspecting signal at the instant when the commercial power source is connected, whereby inspection for emergency operation of the lamp system can be rendered reliable. CONSTITUTION:Timer T is designed such that it is reset at the time when current supply from commercial power source is started and produces a H-level signal, for instance, for 20 minutes after passing of a time (for instance, one week) required for charging battery B to its full capacity. For one week after starting of current supply, switching relay Rx continues to be energized and a signal of L-level is supplied to latch circuit 3, so that alarm lamp AL is not lighted. When output of the timer T becomes H-level, on the other hand, transistor Q1 is turned OFF and relay Rx is de-energized, so that emergency lighting means 2 is set into oscillation by the battery B and thus lamp FL is lighted. If it is not possible that lamp FL is lighted by the battery B as long as 20 minutes, alarm lamp AL is lighted for one week until the time when the next inspection is effected.
